I visited the waterfall as part of a tour group. Very cool place. You can swim right in the lagoon. Monkeys run along the banks. Lots of Indians keeping order. And when the train went over the bridge - the feeling was indescribable!
Visited during a tour! Impressed by the interior and colors. Very competent speech of the guide, Maria, was on top. Externally, the building is impressive, massiveness, grandeur.
